EZCrypto

Easy to use wrapper around cryptographic libraries for Python.

Usage examples

Importing the RSA PrivateKey class

from ezcrypto.pki.rsa import PrivateKey

Generating a new key

private_key = PrivateKey.generate()

Loading a private key from a PEM file

private_key = PrivateKey.load_from_pem_file('/path/to/priv.pem')   

Obtaining the public key

public_key = private_key.get_public_key()

Loading a public key from a PEM file

public_key = PublicKey.load_from_pem_file('/path/to/pub.pem')

Exporting a public/private key as a PEM string

my_key.export_as_pem()

Creating a private key instance from a PEM string

private_key = PrivateKey(pem)

Encrypting data of arbitrary length as Base64

data = my_key.encrypt_as_base64(data)

Decrypting data from Base64

data = my_key.decrypt_from_base64(data)

Signing a message using a private key

signature = private_key.sign(message)

Verifying a message signed with a private key

private_key.verify(message, signature)

Signing the hash of a message using a private key

signature = private_key.sign_after_hashing(message)

Verifying the hash of a message signed with a private key

private_key.verify_after_hashing(message, signature)

NOTES:

• EZCrypto uses PyCrypto for all cryptographic operations.
• Hashing is made using the SHA1 function from Python's hashlib standard module.
